Group B Streptococcus Testing

Group B Streptococcus (GBS) Testing


Group B Streptococcus (GBS) is a type of bacteria that can be found in the digestive tract, vagina, and rectum of some individuals. While it usually does not cause illness, it can lead to serious infections in individuals with weakened immune systems, particularly newborns and pregnant women.  


How does GBS infection occur?

  • In pregnant women: The bacteria may be passed from mother to baby during vaginal delivery
  • In adults: Infection may occur through the urinary tract or open wounds
  • In newborns: GBS can cause severe conditions such as meningitis, pneumonia, or sepsis

Why is GBS testing important?

  • To prevent transmission from mother to child during childbirth
  • To reduce the risk of complications in newborns
  • To allow proper planning for preventive antibiotic treatment during labor if GBS is detected
  • To prevent serious infection in high-risk individuals

Our Testing Technology


  • PCR Hybridization on DNA Microarray Chip
  • Accuracy over 98%
  • Uses probes to directly detect the genetic sequence of GBS
  • Capable of detecting the bacteria even in low concentrations
  • Accepts samples from Urogenital Swab and Rectal swab


Target Organism

  • Group B Streptococcus

Sample Collection Precautions


  • Avoid washing the vaginal or rectal area before sample collection  
  • Avoid using suppositories or topical medications  
  • Samples must be submitted within the following timeframes:

           - Urogenital swab: within 5 days; refrigerate at ≤ 8°C if not submitted immediately

           - Rectal swab: Refrigerated at ≤ 8°C and submitted within 24 hours

What You Will Receive


  • Official laboratory test report
  • Document with QR code for result verification
  • Results indicating whether GBS is "Detected" or "Not Detected"
  • Sample quality and DNA quality assessment  
  • Results can be used to support clinical diagnosis and treatment
